Brown rot is a fungal disease of stone fruits, such as nectarine, peach, apricot, cherry, plum, prune and almond trees. It is caused by the Monomania fructicola fungus.
Brown rot control
Removal of mummies and pruning out diseased tissue is the best solution, once an infestation has occurred. Copper fungicides can be used to minimize fungal populations.
How to prevent brown rot
Pruning for better airflow can reduce the likelihood of infection, as can furrow irrigation. Do not allow sprinklers to wet blossoms.
